Removing Wrinkles from a Pool Liner: Causes and Solutions for Homeowners

Maintain a Smooth and Inviting Pool Surface by Understanding the Reasons Behind Liner Wrinkles and How to Address Them


Wrinkles in a pool liner can be an eyesore and detract from the enjoyment of your swimming pool. They can also potentially cause the liner to wear unevenly or become damaged. To keep your pool in top shape, it’s essential to understand the causes of pool liner wrinkles and the best methods to remove them. In this article, we’ll discuss the reasons behind pool liner wrinkles and provide practical solutions for homeowners to tackle this issue.

Causes of Pool Liner Wrinkles

Improper Installation: Wrinkles can form in a pool liner if it’s not installed correctly. A poorly stretched liner or one that is not properly aligned may develop wrinkles over time.

Groundwater Pressure: Excess groundwater behind the pool liner can cause it to float and develop wrinkles. This can occur due to heavy rainfall, a high water table, or inadequate drainage.

Chemical Imbalance: An improper balance of pool chemicals can cause the liner to stretch, contract, or lose elasticity, which may lead to wrinkles.

Temperature Fluctuations: Sudden or extreme temperature changes can cause the pool liner to expand and contract, leading to the formation of wrinkles.

Solutions for Removing Pool Liner Wrinkles

Manual Adjustment: For minor wrinkles, try gently pushing the wrinkles toward the edge of the pool using a soft brush or pool broom. This method is most effective when the pool water is warm, as the liner will be more pliable.

Partially Drain the Pool: If the wrinkles are more severe, consider partially draining the pool to allow for easier access and manipulation of the liner. Once the water level is lowered, carefully work the wrinkles toward the edge of the pool. Refill the pool slowly to avoid causing new wrinkles.

Use a Plunger: For smaller wrinkles, a toilet plunger can be used to create suction and help move the wrinkle. Place the plunger on the wrinkle and gently push and pull to shift the liner and smooth out the wrinkle.

Install a Pool Liner Lock: A pool liner lock can help secure the liner in place and prevent future wrinkles. This device is installed along the pool’s edge and holds the liner in position.

Professional Assistance: If the wrinkles are severe or the liner is damaged, it’s best to consult a pool professional. They can assess the situation and provide guidance on whether the liner needs to be replaced or can be repaired.

Preventing Pool Liner Wrinkles

Proper Installation: Ensure your pool liner is installed correctly and professionally to avoid wrinkles from the beginning.

Maintain Balanced Chemical Levels: Regularly test your pool water and adjust the chemical levels as needed to prevent liner damage.

Monitor Groundwater and Drainage: Ensure proper drainage around your pool to prevent groundwater pressure from causing liner issues.

Avoid Drastic Temperature Changes: Gradually adjust the pool’s temperature to minimize the effects of temperature fluctuations on the liner.


Pool liner wrinkles can be unsightly and, in some cases, cause damage to the liner itself. Understanding the causes of these wrinkles is essential for prevention and effective removal. Homeowners can take steps to address wrinkles in their pool liners through manual adjustment, partial water drainage, or professional assistance. By taking proper care of your pool liner and maintaining balanced water chemistry, you can enjoy a smooth and inviting swimming pool for years to come.
